1+sin²x=2-cos²x
Remenber:   sin²x+cos²x=1      ⇒sin²x=1-cos²x
 
1+sin²x=1+(1-cos²x)=2-cos² x       (this is true)

Please answer this question for points

Answer:

<h2>y = -2x + -3</h2>

Step-by-step explanation:

Slope-intercept form is y = mx + b

"m" is the slope, how steep the line is.

"b" is the y-intercept, where to graph hits the y-axis.

Check the scale for this grid. Since there are "1" written on the first box after the middle, <u>one square = one unit</u>.

To find "m", use  m = \frac{rise}{run}   between the two dotted points on the graph. The first point is always on the left.

<u>"Rise" means how many squares above</u> the first point the second point is.

Since the second point is below the first point, the number is negative.

<u>"Run" means how many squares to the right</u> the second point is.

m = \frac{rise}{run}          

m = \frac{-2}{1}

m = -2

To find "b", look at where the graph it touching the y-axis.

The y-axis is the vertical line (going from top to bottom).

Count the number of squares from the grid's middle to the graph line.

There are 3 squares.

Since the graph touches below the origin, this is a negative number.

b = -3

In the boxes, you put negative two (-2) and negative three (-3).

* Usually we would simplify the equation to y = -2x - 3.
